이하 본 발명에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 3 내지 도 6에 도시된 바와 같이 방화문(20)에 웰딩플레이트(30)가 용접된 상태에서 롤러(60)와 벨트(70)를 롤러지지축(40)에 의해 설치하는 과정은 벨트(70) 속에 롤러(60)를 끼운 상태에서 자리파기홈(22)을 향해 벨트(70)와 롤러(60)를 옆으로 삽입한 다음 롤러(60)의 중심과 수직관통구멍(36)(26)의 중심을 일치시킨 상태에서 웰딩플레이트(30)에 형성되어 있는 수직관통구멍(36)으로 롤러지지축(40)을 삽입하게 되면, 롤러지지축(40)이 롤러(60)의 중심을 관통하여 바닥면(24)에 형성되어 있는 수직관통구멍(26)으로 삽입된다.3 to 6, the process of installing the roller 60 and the belt 70 by the roller support shaft 40 in the state in which the welding plate 30 is welded to the fire door 20 is performed by the belt. The belt 70 and the roller 60 are inserted laterally toward the digway 22 with the roller 60 inserted in the 70, and then the center of the roller 60 and the vertical through hole 36 (26). When the roller support shaft 40 is inserted into the vertical through hole 36 formed in the welding plate 30 in the state where the center of the center is aligned, the roller support shaft 40 penetrates the center of the roller 60. It is inserted into the vertical through hole 26 formed in the bottom surface 24.

이때 롤러지지축(40)의 상단에 형성되어 있는 두부(44)의 육각홈(44h)에 육각렌치와 같은 공구를 결합하여 돌리게 되면, 롤러지지축(40)의 하단부에 형성되어 있는 수나사부(42)가 웰딩너트(50)에 결합되어 고정된다.At this time, when a tool such as a hexagon wrench is rotated to the hexagonal groove 44h of the head 44 formed at the upper end of the roller support shaft 40, the male screw part formed at the lower end of the roller support shaft 40 ( 42 is fixed to the welding nut 50.

한편, 방화문(20)을 열고 닫게 되면, 방화문(20)의 모서리부분에 설치되어 있는 벨트(70)가 문틀(21)에 설치되어 있는 수평실링재(26)에 접촉되면서 마찰력이 발생되는데, 이때 벨트(70)와 수평실링재(26)의 마찰력에 의해 벨트(70)와 롤러(60)가 공회전되면서 수평실링재(26)의 표면이 손상되는 것을 방지하는 작용을 하게 되며, 방화문(20)이 부드럽게 열리고 닫히도록 하는 작용도 하게 된다.Meanwhile, when the fire door 20 is opened and closed, a friction force is generated while the belt 70 installed at the corner of the fire door 20 comes into contact with the horizontal sealing material 26 installed at the door frame 21. As the belt 70 and the roller 60 are idling by the frictional force of the 70 and the horizontal sealing material 26, the surface of the horizontal sealing material 26 is prevented from being damaged, and the fire door 20 opens smoothly. It also works to close.

또, 벨트(70)를 교체하거나 청소할 필요가 있는 경우에는 롤러지지축(40)을 웰딩너트(50)로부터 분리하게 되면, 벨트(70)와 롤러(60)를 자리파기홈(22)으로부터 인출할 수 있기 때문에 편리하게 교체와 청소가 가능하게 된다.In addition, when the belt 70 needs to be replaced or cleaned, when the roller support shaft 40 is separated from the welding nut 50, the belt 70 and the roller 60 are pulled out from the dent groove 22. This allows for convenient replacement and cleaning.
